Here are some unusual names for you to try, Isuelt/Isyold (pron. isyolt), from the name of an Irish Princess in Arthurian legend. Tamar taken from the name of the river in Cornwall, UK. Elenwen, meaning 'star-maiden' fron Tolkein's elvish language Sindarin. Or to really confuse people with the spelling try a good gaelic name like, Siobhan (shivawn), Sinaed (shinayd) or Niamh (neeve). Good luck!
